Interesting idea, Marko. I probably can't implement your idea exactly as described since I'm rather anal about vacuuming my tanks, but I like the idea of the two colors of green contrasting each other. Maybe I can rework things to use HC and riccia as a contrast. They're not as good a contrast as java moss, but they'd both be anchored down well enough to hold the sand in place while still adding contrasting greens and leaf shapes.
One thing I did that I think may help me keep plants from growing into each other was to create actual dividers in which to plant the swords. I actually created "bowls" in the swirling shape in which I would allow them to grow. It's as if they're in containers without holes. The whole design is created with these bowls of sorts. That way, when I rescape this tank, I can literally lift out various parts without having to "dig up" any of the plants. Well, except the crypt in the far right corner, but that's a plant that can take abuse without showing it.
You're all giving me some ideas for my next scape. Thanks!
